WILLIAM COB/DICE MOLAUGHLIN, OF OAKLAND, CALIVFKORJSTIB..` l

AMALGAMATOR.

Application led February 15, 1,922. Serial No. 536,674.

To all whom it may concern.'

Be it known that l, VILLIAM Cormier MCLAUGHLIN, a citizen of the UnitedStates, residing at Qakland, in the county of Alameda and State ofCalifornia, have invented certain new and useful yImprovements inAmalgamators, of which the following isa specification.

My invention is an improved gold separator, particularly useful forseparating flour gold, which is constructed so that it may be' readilytaken apart to amalgama'te the interior and for repairs. rEheamalgamated gold falls through the separator and lodges in a sump at thebottom.

Referring to the annexed drawing in which my invention is illustratedand which forms a part of this specification:

Figure 1 is a transverse sectional view of my amalgamator.

Figure 2 is a fragmentary side view of the same.

My gold separator includes a plurality of superimposed drums 1, 2, 3 and4, a chute 5y leading at an angle into the uppermost drum 4, .a sump 7below the lower-most drum 1 with which said drum communicates.

In my amalgamator, the rear halves of the drums 1, 2 and 3, the entirechute 5 and the entire sump 7 are formed in one casting 100, while theforward portion of said drums and said sumpy are formed lin one casting101. Angle irons 102 are secured to each side of the casting 100 at theforward edges thereof, with one member of said bars outstanding fromsaid forward edges of said casting. Angle irons 103 are secured to eachside of the casting 101 at the rear edges thereof with one member ofsaid bars outstanding from said rear edges of said casting'and restingagainst the outstanding flanges of the angle bars 102. The outstandingmembers of the angle bars 103 are provided with a series of verticalslots 104. The bolts 53 extend through the slots 104: and screw into theoutstanding flanges of the angle irons 102130 hold the castings 100 and101 in proper relative position. By means of the slots 104 the casting101 may be adjusted vertically with relation to the casting 100 to varythe size of the ports 35, 36, 37 between the drums 3 and 4, 2 and 3 and1 and 2 and the size of the port 38 between the drum 1 and sump 7 re-kspectively. A coarse vertical screen 105 is secured across the front ofthe casting 100 at its lower end to the vsump 7 `and at'its if?" upperedge tothe front wall ofthe'chute 5, said screen extending through theports `35, 36, 37 and 38 and'vdividingthe `drums 1,'12 and 3, the sump 7and thedrum-4 and chute 5. A plurality of semi-circular screens 106 ofdiiferent diameters and ner mesh than screen 105 are securedtothescreen105 concentrically within the rear half of druml, the forwardhalf of drum l2, the rear half of drum 3 and the forward half of drumarespectively. v

The screens 105, 106, 107 and 108 are cope per and are coated withmercury."y The flour gold in passingl through these screens unites withthe mercury and drops intothe sump because of its increased weight.l Thegold passes through the screens with the water and is caused to washfrom side to side and comes into contact with a large amalgamatedsurface in this way so that there is very little possibility of losingany of the gold. l

`A liquid emulsion of sand and flour gold is placed in the chute 5 andpasses from the chute through screen 105, into drum -1 through screens106, 107 and 108 in said drum, then through port 35 into drum 3 throughscreens 105 and screens 106, 107 and 108 in said drum, then through port36 into drum 2 through screen 105 and through screens 106, 107 and 108in said drum, then through port 37 into drum 1 through screen 105 andthrough screens 106, 107 and 108 .in said drum and then through port 38into sump 7 and out, the gold being caught in the screens '106, 107 and108 in the drums 1, 2, 3 and 4 and also in the screen 105. The apparatusis then taken apart and the gold recovered.

Having described my invention, l claim: 1. A gold separator including aplurality of superimposed communicating` drums, v a chute communicatingwith the uppermost drum, a sump communicating with the lowermost drumacoarse screen extending vertically through said drums and said sump. and`a plurality of fine concentric screens of different diameters securedto said coarse screen in each of said drums. 2. A gold separatorincluding a plurality of superimposed communicating drums, a chutecommunicating with the .uppermost drum, a sump communicating with thelowermost drum, a coarse screen extending verplurality ,of fineconcentric screens orn different diameters secured to said Coarse screenin each of said drums, said fine screens being located in alternatesides of said drums'successively.

3. A gold separator including a plurality of superimposed communicatingdrums7 a chute communicating with the uppermost drum, a sumpcommunicating with the lowermlost drum, said chute, said sump and therear half of said .drums being Ytermed in one casting', the, forwardhalf of said drums being formed in another single casting, angle ironssecuredto the rear casting at the for- 4'Ward edges thereof, angle ironssecured to said for-Ward casting at the rear edges thereof, Vandprovided with vver-tical slots in their ,outstanding flanges, boltsextending through 'said 'slots and screwing into the adjacent flanges ofthe angle irons on said rear casting for adjusting castings verticallywith relation to each 'other to Vary the size of the ports'between saiddrums, and means in .said drums'for collecting the gold.

ing formed. in another single casting7 angle irons secured to therear-casting at the forward edges thereof, angle ironsisecured to saidforward Casting at the rear edges thereof, and provided With verticalslots in their outstanding flanges, bolts extending through said slotsand screwing into 'the adjacent flanges o1" the angle irons on said rearcast ing or adjusting said castings vertically with relation to eaohother to vary the size of the ports between said drums, a coarse screenextending through said drums and said sump, and tine screens ofdifferent diameters secured to said coarse screen con*- centrically insaid drums.

ln testimony whereof `afiix my signature.
